Fwiffo: A hint for your next opportunity. ;-) With a joke on a current and controvertial topic you need to make it clear. Drop anything serious (ie. the "commercial" bit) and then "tell" people that it's to be laughed at, either with (joke) or a smiley:

"What? Is Gothic Chess removed from Brainking? Awww, just when I made my own Gothic Chess pieces!!"
;o)
